350-601 Compute Practice Test 11 — 15 Questions

Question 1

Which component in a UCS domain is responsible for aggregating and forwarding all management traffic between the chassis and the fabric interconnects?

Accepted Answer

System controller (CMC). The system controller (also known as the chassis management controller) in the UCS chassis handles management traffic for the blades, including communication with UCS Manager via the FIs.

Answer

CIMC

Answer

Blade BMC

Answer

IOM (FEX)

Question 2

A UCS domain has two Fabric Interconnects (FI-A and FI-B) in a redundant configuration. A blade server is configured with two vNICs: one for FI-A and one for FI-B. What happens if FI-A fails?

Accepted Answer

Traffic is automatically failed over to the vNIC connected to FI-B. When FI-A fails, the blade server's vNIC connected to FI-A becomes unavailable. However, because the vNICs are configured in a redundant pair (active/standby or active/active with failover), the operating system or the Cisco UCS Manager's NIC teaming policy automatically fails over traffic to the vNIC connected to FI-B. This is achieved through the use of MAC address pinning and the failover mechanism inherent in the Cisco UCS fabric interconnect architecture, ensuring continuous network connectivity without manual intervention.

Answer

The blade loses all network connectivity

Answer

Both vNICs are reconnected to FI-B automatically

Answer

The blade continues to use the vNIC on FI-A but without redundancy

Question 3

What is the primary benefit of using UCS service profiles for server deployment?

Accepted Answer

Hardware abstraction and stateless computing. Service profiles abstract hardware configuration, allowing rapid provisioning and stateless computing. A server can be replaced without reconfiguration by simply associating the same service profile.

Answer

Increased network bandwidth

Answer

Reduced power consumption

Answer

Simplified storage zoning

Question 4

A data center administrator is designing a HyperFlex cluster for a virtualized environment. The cluster must be able to tolerate the failure of any two nodes. Which two configuration choices are required? (Choose two.)

Accepted Answer

Minimum of 5 nodes. To tolerate two node failures, the cluster must have at least 5 nodes (with RF3, quorum requires >50% of total nodes; with 5 nodes, quorum is 3, and losing 2 leaves 3, maintaining quorum). RF3 replicates data three times, ensuring data remains available even after two failures.

Answer

Cluster witness VM

Answer

Minimum of 4 nodes

Answer

Replication factor RF2

Question 5

An engineer is configuring a UCS service profile for a blade server that will be used for a critical application. The application requires high availability for both network and storage connectivity. Which three policies should be configured in the service profile to meet these requirements? (Choose three.)

Accepted Answer

SAN connectivity policy. For HA, the service profile should use a VLAN policy for network connectivity, a SAN connectivity policy for storage, and a boot policy that defines multiple paths. Additionally, a vNIC/vHBA placement policy can enable failover, but the core three are VLAN, SAN, and boot policies.

Answer

IPMI policy

Answer

Power policy

Question 6

An organization is deploying UCS C-series rack servers in standalone mode. Which two management capabilities are available through Cisco IMC? (Choose two.)

Accepted Answer

KVM console access. Cisco IMC provides KVM console and virtual media mounting, as well as remote firmware upgrade. These are common out-of-band management features.

Answer

UCS Manager integration

Answer

HyperFlex cluster management

Answer

Fibre Channel zoning

Question 7

An engineer is deploying UCS B-series blades in a 5108 chassis connected to a pair of Fabric Interconnects. To ensure high availability, each blade's vNICs must be pinned to both FIs. Which configuration method should be used in the service profile to achieve this?

Accepted Answer

Create a vNIC placement policy that assigns one vNIC to Fabric A and another vNIC to Fabric B, both without failover.. In UCS Manager, the vNIC placement policy determines how vNICs are assigned to fabric interconnects. Selecting 'fabric failover' allows a vNIC to fail over to the other FI, but for active-active use, multiple vNICs are needed. The correct approach is to use a vNIC placement policy that assigns each vNIC to a specific fabric without failover, combined with proper fabric pinning in the LAN connectivity policy.

Answer

Configure each vNIC with fabric failover enabled, then assign the vNICs to the same fabric.

Answer

Use the default vNIC template which automatically assigns vNICs to both fabrics.

Answer

Enable fabric failover on the uplink ports of the Fabric Interconnects.

Question 8

A UCS C-series rack server is to be integrated into UCS Manager. The server will be managed by CIMC and must participate in compute pools. Which operating mode should be configured on the C-series server to allow UCS Manager to discover and manage it?

Accepted Answer

UCS-managed mode. C-series servers can operate in standalone mode (IMC only) or UCS-managed mode. To be managed by UCS Manager, the server must be in UCS-managed mode, which requires enabling UCSM (Cisco UCS Manager) mode in CIMC.

Answer

Cisco IMC Supervisor mode

Answer

Direct connect mode

Answer

Standalone mode

Question 9

A HyperFlex cluster uses replication factor 3 (RF3) and consists of 4 all-flash nodes. One node fails permanently. After replacing the node, the cluster re-replicates data. What is the minimum number of additional node failures that can be tolerated without data loss after re-replication completes?

Accepted Answer

2. With RF3 (three copies of data), the cluster can tolerate up to two simultaneous failures (quorum requires at least two copies). After replacing the failed node, the cluster returns to full health, so again can tolerate two failures. However, if the cluster originally had 4 nodes and one fails, only 3 remain; if another fails during re-replication, data could be at risk. But after re-replication, 4 nodes exist, so two failures are tolerable.

Question 10

An administrator needs to replace a faulty UCS B200 M5 blade with a new blade of the same model. The original blade had a service profile associated. What is the minimum required action to allow the new blade to take over the workload with the same configuration?

Accepted Answer

Disassociate the service profile from the faulty blade and associate it with the new blade.. UCS service profiles provide hardware abstraction, making blades stateless. Simply inserting the new blade will not automatically associate the profile; the administrator must re-associate the service profile with the new blade. No other reconfiguration is needed if the new blade is identical.

Answer

Clone the service profile and then associate the clone with the new blade.

Answer

Manually reconfigure the new blade via the KVM console.

Answer

Update the firmware on the new blade to match the service profile requirements.

Question 11

A UCS B-series blade is configured to boot from SAN using a vHBA that connects to a Fibre Channel SAN. The storage administrator reports that the LUN is not being presented to the blade. Which component in the UCS domain is responsible for mapping the vHBA WWPN to the physical Fibre Channel interface?

Accepted Answer

Fabric Interconnect. In UCS, the Fabric Interconnect (FI) acts as a Fibre Channel forwarder (FCF) or NPV switch. The vHBA's WWPN is assigned by UCS Manager and the FI maps it to the appropriate uplink Fibre Channel interface. The UCS Manager itself configures this mapping, but the actual mapping occurs on the FI.

Answer

IOM (FEX)

Answer

CIMC

Answer

UCS Manager

Question 12

Which HyperFlex node type offers the best performance for all-flash workloads and does not include HDDs?

Accepted Answer

All-flash. HyperFlex supports hybrid nodes (HDD+SSD cache) and all-flash nodes (SSD only). All-flash nodes provide higher performance and no HDDs.

Answer

Compute-only

Answer

Hybrid HDD/SSD

Answer

Storage-only

Question 13

An organization uses UCS Central to manage multiple UCS domains. A global service profile policy is created in UCS Central to enforce a common boot policy across all domains. However, one UCS domain needs a different boot order for a specific set of blades. How should the administrator implement this deviation while maintaining centralized manageability?

Accepted Answer

Create a local boot policy in the specific UCS Manager and assign it to the service profiles that need the change.. UCS Central allows global policies, but local policies in each UCS Manager can override them for specific service profiles. The administrator should create a local boot policy in the specific UCS domain and assign it to the service profiles that require the different boot order.

Answer

Exclude the specific UCS domain from the global policy and create a separate global policy for that domain.

Answer

Delete the global boot policy and use only local policies.

Answer

Modify the global boot policy in UCS Central to include all variations.

Question 14

A UCS C-series server is deployed in standalone mode and managed via CIMC. The administrator needs to mount an ISO image for OS installation. Which CIMC feature should be used to remotely attach the ISO?

Accepted Answer

Virtual media. CIMC provides virtual media functionality, allowing mounting ISO images as virtual CD/DVD drives over the network.

Answer

KVM console

Answer

Serial over LAN

Answer

Remote firmware update

Question 15
